Detailed Description

object represents upward pointers from points to list of cells using each point

vtkCellLinks is a supplemental object to vtkCellArray and vtkCellTypes, enabling access from points to the cells using the points. vtkCellLinks is a list of Links, each link represents a dynamic list of cell id's using the point. The information provided by this object can be used to determine neighbors and construct other local topological information.

Member Function Documentation

static vtkCellLinks* vtkCellLinks::New ( ) [static]

Create an object with Debug turned off, modified time initialized to zero, and reference counting on.

Reimplemented from vtkObject.

virtual const char* vtkCellLinks::GetClassName ( ) [virtual]

Reimplemented from vtkObject.

static int vtkCellLinks::IsTypeOf ( const char * name ) [static]

Return 1 if this class type is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h.

Reimplemented from vtkObject.

virtual int vtkCellLinks::IsA ( const char * name ) [virtual]

Return 1 if this class is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h.

Reimplemented from vtkObject.

static vtkCellLinks* vtkCellLinks::SafeDownCast ( vtkObject * o ) [static]

Reimplemented from vtkObject.

void vtkCellLinks::PrintSelf	(	ostream &	os,
		vtkIndent	indent
	)			`[virtual]`

Methods invoked by print to print information about the object including superclasses. Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes.

Reimplemented from vtkObject.

void vtkCellLinks::Allocate	(	vtkIdType	numLinks,
		vtkIdType	ext = `1000`
	)

Allocate the specified number of links (i.e., number of points) that will be built.

Link& vtkCellLinks::GetLink ( vtkIdType ptId ) [inline]

Get a link structure given a point id.

Definition at line 55 of file vtkCellLinks.h.

unsigned short vtkCellLinks::GetNcells ( vtkIdType ptId ) [inline]

Get the number of cells using the point specified by ptId.

Definition at line 58 of file vtkCellLinks.h.

void vtkCellLinks::BuildLinks ( vtkDataSet * data )

Build the link list array.

void vtkCellLinks::BuildLinks	(	vtkDataSet *	data,
		vtkCellArray *	Connectivity
	)

Build the link list array.

vtkIdType* vtkCellLinks::GetCells ( vtkIdType ptId ) [inline]

Return a list of cell ids using the point.

Definition at line 67 of file vtkCellLinks.h.

vtkIdType vtkCellLinks::InsertNextPoint ( int numLinks )

Insert a new point into the cell-links data structure. The size parameter is the initial size of the list.

void vtkCellLinks::InsertNextCellReference	(	vtkIdType	ptId,
		vtkIdType	cellId
	)			`[inline]`

Insert a cell id into the list of cells (at the end) using the cell id provided. (Make sure to extend the link list (if necessary) using the method ResizeCellList().)

Definition at line 155 of file vtkCellLinks.h.

void vtkCellLinks::DeletePoint ( vtkIdType ptId ) [inline]

Delete point (and storage) by destroying links to using cells.

Definition at line 147 of file vtkCellLinks.h.

void vtkCellLinks::RemoveCellReference	(	vtkIdType	cellId,
		vtkIdType	ptId
	)			`[inline]`

Delete the reference to the cell (cellId) from the point (ptId). This removes the reference to the cellId from the cell list, but does not resize the list (recover memory with ResizeCellList(), if necessary).

Definition at line 162 of file vtkCellLinks.h.

void vtkCellLinks::AddCellReference	(	vtkIdType	cellId,
		vtkIdType	ptId
	)			`[inline]`

Add the reference to the cell (cellId) from the point (ptId). This adds a reference to the cellId from the cell list, but does not resize the list (extend memory with ResizeCellList(), if necessary).

Definition at line 182 of file vtkCellLinks.h.

void vtkCellLinks::ResizeCellList	(	vtkIdType	ptId,
		int	size
	)			`[inline]`

Change the length of a point's link list (i.e., list of cells using a point) by the size specified.

Definition at line 188 of file vtkCellLinks.h.

void vtkCellLinks::Squeeze ( )

Reclaim any unused memory.

void vtkCellLinks::Reset ( )

Reset to a state of no entries without freeing the memory.

unsigned long vtkCellLinks::GetActualMemorySize ( )

Return the memory in kilobytes consumed by this cell links array. Used to support streaming and reading/writing data. The value returned is guaranteed to be greater than or equal to the memory required to actually represent the data represented by this object. The information returned is valid only after the pipeline has been updated.

void vtkCellLinks::DeepCopy ( vtkCellLinks * src )

Standard DeepCopy method. Since this object contains no reference to other objects, there is no ShallowCopy.

void vtkCellLinks::IncrementLinkCount ( vtkIdType ptId ) [inline, protected]

Increment the count of the number of cells using the point.

Definition at line 118 of file vtkCellLinks.h.

void vtkCellLinks::AllocateLinks ( vtkIdType n ) [protected]

void vtkCellLinks::InsertCellReference	(	vtkIdType	ptId,
		unsigned short	pos,
		vtkIdType	cellId
	)			`[inline, protected]`

Insert a cell id into the list of cells using the point.
